Anchoring is an issue which all thoughtful judges need to be aware of.  Mark W. Bennett has posted Confronting Cognitive ‘Anchoring Effect’ and ‘Blind Spot’ Biases in Federal Sentencing: A Modest Solution for Reforming a Fundamental Flaw (Journal of Criminal Law and Criminology, Vol. 104, No. 3, p. 489, 2014) on SSRN.  Although the article is focused upon federal sentencing practices, it contains lessons for all judges.

Here is the abstract:

Cognitive “anchoring effect” bias, especially related to numbers, like sentencing guidelines ranges, is widely recognized in cognitive psychology as an extremely robust and powerful heuristic. It is a cognitive shortcut that has a strong tendency to undermine judgments by “anchoring” a judgment to an earlier disclosed number, the anchor. Numerous studies prove anchoring bias produces systematic errors in judgment in wide-ranging circumstances, including judgments by experts — doctors, lawyers, real estate agents, psychologists, and auditors — as well as a variety of decisions by foreign and American federal and state judges. The anchoring effect occurs even when the anchor is incomplete, inaccurate, irrelevant, implausible, or even random. Roughly corresponding in time with the developing understanding of the anchoring effect, federal sentencing has undergone a revolution from judges having virtually unlimited discretion, to virtually no discretion, and back to considerable discretion, as the Federal Sentencing Guidelines went from mandatory to advisory in a single monumental U.S. Supreme Court decision, United States v. Booker, 543 U.S. 220 (2005). Surprisingly, since judges were granted much greater discretion in Booker, the length and severity of federal sentences, for the most part, has not changed. This remains true despite long-standing, persistent, and widespread dissatisfaction among federal district court judges with the Guidelines and the length of sentences. This Article argues that this is because judges’ sentences are subconsciously anchored by the calculated Guidelines range.
